Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a front wall and a rear wall of flexible material, the rear wall being provided with openings to allow waste material to enter the bag and further to the wearer of the bag. The present invention relates to a surgical collection bag for collecting human waste, which has an attachment means for attaching to a body and a vent hole provided in one of the front wall and the rear wall. Furthermore,
The invention particularly relates to ostomy bags and methods of using the same.

[0002]

BACKGROUND OF THE INVENTION Ostomy bags are used to collect feces from ostium surgically formed to reach part of the patient's intestine into the skin of the abdomen. Such bags are typically made of a flexible plastic material and are typically attached to the patient by an adhesive provided on the bag itself around the opening or to a separate patient attachment that allows the bag to be removed and attached. The bag is generally provided with a vent hole through which intestinal gas can escape. In addition, a filter, for example, a filter incorporating activated carbon can be provided in the vent hole so as to reduce the odor generated from the vented gas.

[0003]

One of the problems associated with ostomy bags is the problem of flattening, or "pancaking." The feces do not fall from the bag opening at the bottom of the bag, but collect on the front wall of the bag opposite to the opening. Accumulation of feces in this area may obstruct the opening to the bag and cause feces to leak from the seal between the bag and the skin or the seal between the bag and the patient mount or the seal between the patient mount and skin. There is. Further, in some cases, the bag may come off. The risk of pancaking often occurs when the front wall is close to the opening.
Since the bag is supplied in a flat condition, it is common for the front and rear walls to be in contact with or close to each other when the bag is removed from the package.
Attaching the bag to the wearer may include pressing the front wall rearward against the skin and bringing the back wall of the bag into contact with the skin or patient mount. Provide ventilation holes in the bag. In this case, after mounting the bag, the front wall of the bag is grasped and pulled forward from the rear wall to allow air to flow into the bag through the opening and the vent opening. This initially reduces the risk of pancakes, but the air in the bag gradually escapes from the vent openings (eg, due to external pressure from the garment) and the front wall recedes back toward the opening. Therefore, the risk of pancakes is again increased. If the bag does not have vent holes, the front wall cannot be pulled forward due to the vacuum condition, creating this dangerous condition.

Another problem with vented bags is the problem of attaching a filter to the vent opening. That is, it is necessary to efficiently perform the filtering operation of the bag and avoid expensive assembling work.

Accordingly, it is an object of the present invention to provide a surgical collection bag that can be used to solve these problems.

[0006]

To achieve this object, the surgical medical collection bag according to the present invention can separate the front wall from the rear wall when the vent hole is opened.
Further, the vent hole can be sealed so that gas is blocked in the bag when the vent hole is closed.

In the preferred embodiment, the vent openings include:
A filter is provided to reduce the odor of gas generated from the ventilation holes. The ventilation hole is an opening provided on one wall,
The filter is disk-shaped having a lateral dimension smaller than the aperture, and a gas impermeable member is attached around the aperture on the outer surface of the one wall and to the outer surface of the filter to open the filter. The gas impermeable member is provided with a through opening overlapping with the filter so as to allow the gas to escape from the bag through the filter and the opening when the ventilation opening is opened. Be configured so that The inner surface of the filter is made gas impermeable, and the gas flow is configured to flow radially from the edge of the filter to the opening of the gas impermeable member. Two ventilation passages are provided in the ventilation hole, one of these passages is provided with a filter, and the other passage is provided without a filter. The vent opening is provided with a flexible adhesive strip that can seal the vent opening. The two ventilation passages are opened at positions separated from each other, and either of the ventilation passages can be exposed by peeling off the flexible adhesive strip.

Further, the present invention comprises a front wall and a rear wall of flexible material, the rear wall being provided with openings to allow waste material to enter the bag, and further to attach the bag to a wearer. A method of using a surgical medical collection bag for collecting human waste, comprising: a mounting means for storing the gas; and a vent hole provided in one of the front wall and the rear wall, wherein the vent hole is opened. And a step of separating the walls from each other to allow air to enter the bag through the ventilation hole, and sealing the ventilation hole to close the air in the bag,
Maintaining the two walls separated from each other in the area of the opening.

[0009]

The preferred embodiments of the present invention will now be described with reference to the drawings.

The ostomy bag assembly has a two part construction and includes a patient mount 2 and a collection bag 4. The patient mount 2 comprises a bendable plastic disc 20 having an adhesive back surface 21 which, in use, is attached to the wearer's skin 6 around the stoma 8 and the stoma 8 is opened at the center of the mount. Plunge into hole 24. A shallow collar 26 projects around the central aperture 24 and is used to position the bag 4.

The bag 4 is constituted by a back wall 40 and a front wall 42 of flexible plastic material and seals together around an outer edge 44 to form a toilet disposable. The front wall 42 is free of continuous holes and is outward on the side away from the wearer's skin. The rear wall 40 has an opening 46 with a diameter of about 75 mm,
A flexible flange 47 having a diameter of approximately 95 mm is provided with a back adhesive surface that adheres to the inside of the wall 40 around the opening 46. The flange 47 has a central opening 48 with a diameter of approximately 25 mm.
Is provided so that the substance discharged from the small hole 8 can enter the bag 4. The exposed portion in the aperture 46 in the rear wall 40 of the flange 47 creates an annular adhesive area 49 on which the bag can be attached to the front of the patient mount 2.

A circular first vent opening 50 having a diameter of about 25 mm is provided in the rear wall 40 just above the opening 46. A circular disk filter 52 of activated carbon fibers having a diameter of about 23 mm is placed in the first vent opening 50. The gas impermeable material layer 53 is bonded to the inner surface of the filter 52, and the transparent tape 62 is attached to the outer surface of the filter.
The filter 52 is covered with the tape 62, and the filter 52 is overlapped with the filter 52 and attached to the outer surface of the rear wall 40. On tape 62,
An opening 54 having a diameter of about 2 mm is provided at the center of the filter 52. Layer 53
Prevents the gas flow from passing through the inner surface of the filter 52, so that the gas flow passes radially inward from the edge of the filter and exits through the opening 54 in the tape 62. In this way
The long gas path through the filter results in extremely high filtration efficiency. Flow from the edge into the filter 52 is facilitated by the clearance between the edge of the filter and the aperture 50. In this way, the filter can be easily attached by the automatic assembling work, and the filtering action can be efficiently performed.

Alternatively, the disc filter can be located inside or outside the bag.

The bag 4 is further provided with a second ventilation passage formed by an unfiltered second ventilation opening 60, which is arranged at a position about 18 mm to the left of the ventilation opening 50 with a filter. .. The diameter of the second ventilation hole 60 is about 3 mm, and it directly opens to the bag. The tape 62 is overlaid on the area around the aperture 60 to provide an alignment aperture 64 that aligns with the vent aperture 60.

The area around the two openings 50, 60 is protected by a tape 62 attached to the outer surface of the rear wall 40. Tape 62
It can be a self-winding, single-sided pressure sensitive adhesive tape sold by 3M Company under code 8415.

The bag 4 has a ventilation sealing tape 66 as a tape.
It is attached to the rear surface of 62 and covers both openings 50 and 60 to prevent the passage of gas. Tape 66 is of the same material and dimensions as tape 62 and is aligned with lower tape 62 and the adhesive side of the sealing tape is in contact with the non-adhesive side of the lower tape. Two peeling tabs 67 and 68 formed by paper slip are provided at both ends of the seal tape 66, and are attached to the adhesive surface of the tape. This way, either tab 67, 68
The tape 66 can be peeled off by grasping. This allows
It is possible to prevent the lower tape 62 from being disturbed, that is, the force required to remove the peeling mode sealing tape 66 is small as well as the force required to remove the lower tape in the cutting mode.

Although the ventilation holes 50, 60 can be sealed by the sealing tape 66 alone without the lower tape 62, the wall 40 of the bag is stretched by the action of peeling the sealing tape 62.
It leads to wrinkles. This is a seal tape
It becomes difficult to re-attach 66 and make an effective seal.

This assembly is used as follows. Attach the patient mount 2 to the skin 6 around the stoma 8 as usual.
Attach to. Vent holes 5 on both sides with sealing tape 66
The bag 4 is held at the level of the patient mount 2 with 0, 60 closed and the adhesive area 49 around the bag opening 46 is glued to the front of the patient mount. To produce an effective seal,
The user needs to press the front wall 42 firmly against the adhesive area 49 and press it onto the patient mount 2. This also has the effect of expelling most of the residual air in the bag 4 from around the joint with the patient mount 2, after which the sealing is complete.

After securely attaching the bag 4 to the patient mount 2, the user may allow air to flow into the bag if desired.
The risk of pancaking can be reduced.
This is done by peeling off the sealing tape 66 and exposing the vent holes 60 without filters. The user then grabs the front wall 42 and pulls it forward from the rear wall 40. As a result, a reduced pressure is generated in the bag 4 and the air flows in through the ventilation opening 60. The user opens the sealing tape 66 by 60
Extend it flat and reapply so that no air escapes from the bag. In this way, the air trapped inside keeps the front wall 42 away from the back wall 40, significantly reducing the risk of faeces entering the bag accumulating on the back wall.

When gas accumulates in the bag 4, the user peels off the sealing tape 66 to expose either the filter-equipped vent hole 54 or the non-filter vent hole 60 as desired. The gas can escape until the bag 4 reaches a predetermined inflation level and the sealing tape 66 is reapplied.

When the user feels that there is no problem of flattening, the user peels off the sealing tape 66, folds a part of the adhesive surface of the sealing tape back to adhere to the adhesive surface itself, and leaves the tape attached to the bag. To permanently expose the vent hole with filter, and to
60 can be sealed.

The present invention may be used in other two part assemblies, such as those described in EP 476847. However, the bag is not limited to the two-part bag assembly, and can be used for a bag that is directly attached to the user's skin.
